In its current form, this question is not a good fit for this site. Any question that solicits the creation of a list of source is unacceptable. The individual questions you gave as examples, on the other hand, would be a perfect fit. I have to close this question, but I would strongly suggest you ask the other questions separately.

I have a copy of First World War Atlas by Martin Gilbert (SBN 297 17847 4).

There are a couple of fascinating maps near the end.

Footnote:

War debts were payable to the U.S. over 62 years at an interest rate of just over 2%. Armenia never came into existence as an independent state, and thus none of its debt was paid. Finland alone of 19 nations had paid her debt in full by 1969. In 1925 the United States cancelled 80% of the Italian debt. In 1926 60% of the French debt was cancelled. The Bolshevik Government of Russia rejected the demand that it honour Tsarist debt.
